[PATCH] fbcon: Console Rotation - Add ability to control rotation via sysfs
Add ability to set rotation via sysfs. The attributes are located in /sys/class/graphics/fb[n] and accepts 0 - unrotated; 1 - clockwise; 2 - upside down; 3 - counterclockwise. The attributes are: con_rotate (r/w) - set rotation of the active console con_rotate_all (w) - set rotation of all consoles rotate (r/w) - set rotation of the framebuffer, if supported. Currently, none of the drivers support this. This is probably temporary, since con_rotate and con_rotate_all are console-specific and has no business being under the fb device. However, until the console layer acquires it's own sysfs class, these attributes will temporarily reside here.
